 You need to create a Catalog for every physical star schema that needs to participate in segmentation. Typically, this requires performing the following tasks: 
Creating new catalogs.
Dragging presentation columns from other reporting catalogs into the appropriate segmentation catalogs.
If certain measures are absent in existing reporting catalogs, they need to be brought into the segmentation catalogs from the business model layer.
Do not bring level-based measures in to the segmentation catalog, unless there is a specially mapped measure that improves performance drastically. The Marketing module user interface provides for aggregating measures.
Do not bring in measures that are ratios based on a combination of stars. For example, Opportunity to Order Conversion Ratio. Remember, each segmentation catalog should contain information from one star only.
When marketers want to segment on a star where they want to counts customers where the rows in the fact table satisfy a certain criteria then the fact table can be mapped as a dimension also. For example, if a marketer wants to find customers where any of their orders is greater than $50, then to support this kind of a querying, the order fact logical table needs to be mapped as dimension. |
